Request: Add a class or some other defining feature to "session" objects

Right now, a session is simply an environment and there isn't a proper way to test if is indeed a session of or.
Winston mentioned this is how shiny currently does it in a hacky way

We've fixed this. You can now test the class like this:

  if (!inherits(session, "ShinySession"))
    stop("'session' is not a ShinySession object.")
